SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate and organize product discovery thinking into an Opportunity Solution Tree that maps outcomes to opportunities, potential solutions, and experiments.

Core Features & Use Cases

Top-down outcome-first discovery: define measurable outcomes and align opportunities beneath them.
Multi-branch opportunity space: create multiple leaf opportunities with varied confidence levels and sources.
Solution options per opportunity: propose 2-3 concrete, scalable solutions with distinct scope.
Explicit assumption tests: attach riskiest assumptions and plan small experiments to validate them.
Rendered diagrams: output a Mermaid diagram for team communication.

Quick Start

Describe your desired outcome, and the skill will generate an OST with opportunities, solutions, and experiments.

FAQPage Schema

How do I create an opportunity solution tree for product discovery?▼

An opportunity solution tree connects a desired outcome to opportunities, solutions, and experiments. You define a measurable outcome, and the skill generates a hierarchical tree with multiple solution options and assumption tests for each leaf opportunity.

What is the best way to map product hypotheses to experiments visually?▼

Mapping product hypotheses to experiments involves attaching riskiest assumptions to leaf opportunities and planning small tests. The skill outputs a Mermaid diagram that visually renders these explicit hypothesis tests alongside potential solutions for team communication.

Can I generate multiple solution options for a single product opportunity?▼

Yes, you can generate multiple solution options for a single product opportunity. The skill proposes two to three concrete, scalable solutions with distinct scopes for each leaf opportunity within the hierarchical opportunity space.

How do I structure product discovery from a top-down outcome?▼

Structuring product discovery from a top-down outcome requires defining a measurable target, then aligning multiple leaf opportunities beneath it. The skill supports this workflow by generating a tree with varied confidence levels and sources for each branch.

Does this opportunity solution tree tool require any dependencies?▼

No dependencies are required to generate an opportunity solution tree. You simply describe your desired outcome, and the skill produces the full discovery structure with opportunities, solutions, experiments, and a rendered Mermaid diagram.

When should I use an opportunity solution tree instead of a flat product backlog?▼

Use an opportunity solution tree when you need to validate problems and design testable experiments in product discovery. It maps outcomes to opportunities and explicit assumption tests, providing a hierarchical structure that a flat backlog lacks for managing confidence levels.
